It’s 1928 and the fight for women’s suffrage has faded from its revolutionary ardour in the 1900s into a muted movement, its core of fierce women gradually dropping off. All that remains are nostalgic talks and lectures which, all too often, preach to the converted or to those who’ve come for shocking tales of riots and hunger strikes. The world has moved on. A whole generation of young men has been wiped out in the War. There are other things to worry about than the political ambitions of a group of uppity women. Former suffragettes have married and had children, emigrated, or surrendered to personal demons. But, for Mattie Simpkin, the struggle never ended. This robust, good-hearted, forceful woman lives in a cottage (‘the Mousehole’) just off Hampstead Heath with her companion, meek Florrie Lee (who is, inevitably, nicknamed ‘the Flea’). Mattie is almost sixty, but is determined not to settle down and give up the good fight. Instead, galvanised by the discovery that young women no longer seem to have any kind of gumption or political engagement, she comes up with a plan to correct this – a plan which works wonderfully, except for one tiny, unforeseeable detail.
